We have been using magnets for 5 or 6 years waiting for curtains to arrive. The magnets are 3/4" square and 1/4" thick. They are super magnets and they are dangerous. If they snap together they will take a piece of meat with them. I usually use the 1/4" side if I'm just sticking them to the wall. If you lay them flat you can't get them off.I have to slide them to a curved surface to get them off. Believe me they do work.
I for got where I go them but they aren't hard to find. Just Google super magnets. A pretty good temporary fix.

I am with Jerry we have magnets for our curtain needs and they have been awesome. A bit less powerful magnets that Jerry sounds dangerous but we have been happy with the availability to easily remove the curtains and wash them easily as well as not having all the mounting headaches and holes to deal with. Plus to make curtains without the run in them for curtain rods really made sense for a newbie sewer like myself.

No, we're a gospel quartet. Out on weekends only. Heat...well.....we will be taking this although uncompleted, on its first trip in a couple weeks. Going to probably just bring along a "Mr Heater Big Buddy" for this time. Eventually I am leaning to using either the Webasto or put a water heater with a heat exchanger inline. Still hedging on what to do.
